The SolarMutex is integrated with native gtk+ toolkit locking so
this is semantically equivalent and rather less problematic.

Improvements include:
- don't create widgets when calculating the native region size, but use
  GtkStyleContext instead
- refactor the native control drawing cycle
- theme scrollbars
- theme menu radios/checks/separators/arrows

This also finishes the uncoupling of NSS from the --with-system-mozilla.

.hdl failed to declare the inline cppu_detail_getUnoType functions defined in
.hpp, which if client code only includes .hdl instead of .hpp could lead to
runtime failures, now leads to compiler warnings.

Those bootstrap variables now support <XXX>* syntax to include all files (non-
recursively) contained in the directory denoted by XXX.  Optional components can
put their data simply into program/services/ and program/types/.

do not test if named ranges exist on file load

Added a new compatibility option to keep the previous behavior, but
changed the default to avoid lines insertion for tabs when there are tab
stops set beyond the end margin

Keeping a temporary copy of the shared_ptr to avoid the object to be
deleted during the Select method.
